ahh hum. Sorry, just woken up!
Well that was my favorite part of living in japan. You're pretty much on your own. My advice - youtube mate. youtube.
Not sure if you have any money but a trip to Handsu might be in order. They have quite a range or shaptons and kings and naniwas sitting right on the shelf. Shinjuku has the whole range of each of them, and they're quite cheap! Ah japan.
Your 250/1000 looks a little dodgy to me. If I were a beginner honer I'd prefer to use one a little longer and possibly more consistent.
My advice is to take your time, and embrace the loneliness.
Sorry if post is not coherent - I'm enjoying some new year's guiness! (not in japan)
